Contents: The relationship between obesity and mortality rate is complex -- Differences in associations and causal effects may exist both within and across species -- Obesity is clearly associated with elevated mortality rate and this association is generally presumed to reflect causation -- The epidemiological evidence regarding the effect of being overweight (but not obese) is less clear and more controversial -- Epidemiological evidence on the effects of weight loss on mortality rate among obese persons is even less clear -- Evidence seems to suggest that weight loss induced by methods generally recommended by the biomedical community will prolong life among obese persons -- Data strongly suggest that losing body fat, as opposed to just body weight, is what conveys the presumed benefit of weight loss on longevity.
